Abstract
An impact resistant clad composite armor which includes a ceramic core, and a layer of bulk amorphous alloy surrounding the ceramic core and preferably bonded chemically to the ceramic core and a method of manufacturing such armor is provided.
Claims23
A ceramic armor comprising:
- a ceramic core;
- and
- a metallic layer formed from an amorphous alloy having a yield strength of at least 1.6 GPa and an elastic strain limit of at least 1.2%, the amorphous alloy encapsulating the ceramic core such that the metallic layer places the ceramic core under a compressive stress of at least 400 MPa, wherein at least a portion of the metallic layer formed from an amorphous alloy has a thickness of about 0.5 mm or more.
